37 yrs at Pratt&Witney, you need to get that engine in a concrete test cell before someone gets hurt in the catastrophic failure that will occur . Great development good luck 👍🏍️🇨🇦
I doubt that thing is functional at all as an engine. The flame looked too slow, the sound was fake. Why would they start/test such engine with an after burner on since the very start?
@@VerxxYT That footage was not played at 25% look at the movement of the plants, the oscillation matches how plants move with wind in real time. Still why the fake sounds? They even added a fake alarm car sound.
@teresashinkansen9402 idk man,low weight objects move extremely fast when lots of thrust is around so when it'd slowed , we underestimate how fast its actually moving
@@VerxxYTyou don’t understand. The flame wasn’t supersonic. Which means it’s not pushing the engine with supersonic force. Which means the plane won’t go supersonic. Of course. We’re looking pretty early on. They aren’t even at a proper test facility(the engine is behind glass for gods sake) so it isn’t really meant to do cool stuff yet. But it’s just bad looks
The fact that their using LNG is a big plus, but my only recommendation to them is do not over engineer the engine. It needs to be robust and easily maintainable. That’s the main reason Concorde failed. It used a lot of expensive jet fuel and was really hard to maintain. You got the fuel part down, just make it easy to maintain.
just a s/o to s3 real quick. these videos on startups are inspirational. I am always left with goosebumps and borderline tears knowing that the world is reentering a renaissance. it inspires me to work on my startup every day. thanks bro!
This is interesting. The mechanical decoupling of the hot section from the cold section and drive each via electric motors is actually quite novel.....Probably able to get rid of reduction gearboxes and shafting etc. I'm no engineer, but will follow this closely. I wish them success.
7 to 10 years from now for commercial passengers is...optimistic. I think if you can get there within 20, I'll be super impressed. More likely, you get bought out by GE or Rolls Royce in 5 to 8 years. Maybe Lockheed if you're really lucky and the mission doesn't conflict with your team's vision for the tech.
FAA might like a word on how it's an old custom to delay things at least 4000% percent. in GER it could very well mean that we'd have to wait at least 3 decades.
That wall is probably made from very strong ballistic material. You can't tell what the thickness is of the glass, it's probably very thick bullet resistant tight material. For the wall itself you could use something like AR 500 ballistic metal plate about an inch thick or basically any high carbon 1-inch thick tempered steel plate. The wall wouldn't look very thick but it would be very robust. I would bet that they used good materials in the construction of it.
Because that "engine" is not producing any serious thrust, is fake, they had to fake the sounds because it would be too obvious is just a giant ducted fan with an "afterburner".
The title of this video is quite simply incorrect. Electricity may be used as a coupling mechanism, but it is NOT the power SOURCE -- that is the jet fuel. I definitely would like to congratulate the team on this success--thinking outside convention about how to make existing technology more efficient. If the turbine/generator is the most efficient way to convert jet fuel to electricity, then this could open up the field for hybrid, electric motor powered aircraft, like the VTOL models that are range limited by battery technology.
@@s3_build isn't it still quite wrong? and while I recognize that you can use electric transmission in a jet engine instead of gears or wider turbines, isn't it the case that for supersonic cruise there is no particular need for steep gearing so direct shaft is best and your claim that range would be significantly increased is a lie? that better range is better had in weight reduction which concorde had good opportunity for
@@s3_build Thank you so much for doing that and departing from the horrible trend of UA-cam channels being sensational and using distracting titles/content.
I’m already in love with that team the strategy the vision the execution validation etc., and me coming from product development I really really really impressed of what I’m watching here
Really interesting idea. I’m always hesitant to put too much stock into electrifying high energy, traditionally mechanical systems. If they have the numbers to show that even after the electric inefficiency losses, the adaptive regimes are a net gain, that would be really awesome. Best of luck.
Shout out to S3. I can tell you’ve really found a passion with this channel and I love watching it continue to grow while learning about the future at the same time. Cheers
The timeline for these projects is just insane compared to saas businesses. Love to have these companies with 10 year timelines. Really puts things into perspective.
Very exciting! Great work by the team Your content, interview style, the direction is amazing! Your research on finding these companies which are literal gems is great, just love your videos
Wow!, interesting. Love that the compressor and Turbine are completely decoupled. Would really like to see the P-V and T-S diagrams for a cycle like this. I have experience with engine controls, performance and operability for 2 major Gas turbine manufacturers and I find this super interesting.
Fantastic ideas and workmanship. Maintain analogue control plus digital control, incase digital fails. magnetically coupled and Supercharged turbo jet. That's a bad ass engine and this is a great production.
@Bronilli Yep, RealEngineering did a whole video and more on it. But they don't use the same setup this one uses. Their core principle is to make off the shelf tech work. Their jet engine on the main production vehicle is just a modified prat and whitney. The part they innovate is adding and intercooler to push the engines power during the supersonic to hypersonic transition and bypass ducts to enable the ram jet effect.
@@cyrusesfahani5935 I’m imagining the ultimate jet engine being a combo of this and the hermeus. Stick it in a 1 or 2 seater private aircraft and have it like a personal sports car in the air that can get you anywhere in the world in like 3 hours
Very nicely produced video. You all have innovator’s spirit and it really comes through in the footage. I’m very curious about the thrust your engine produces; I’m a bit surprised you didn’t mention it, and I’m assuming your test rig isn’t set up to measure it. Also would like to see an overview of some Mean Time Between Failure stats compared to a conventional jet engine. This is cool idea and I hope you have success with it.
had seen some development in the 80's from old salts. Getting the efficency up of electrics is important as it kills you. Electric gearbox is a fun idea as they say great to balance the curve and efficencies of the various rotors. There were some people using a magnetic gearbox doing a similar thing. wish them luck as the tech maybe there now
Great video! Love seeing all these companies and engineers who are so passionate about building stuff to move us into the future!! One note/suggestion, I found it frustrating when the opening scene the engine test cut to black, I would've loved to see that at the beginning without the cut to black and then learn why they're doing it. Anyways, keep it up!
Great video; awesome production quality and an awesome topic/start-up. Seems like a novel idea and hats off to them for starting what could be a new generation of jet engines with an increased range of efficiency... my only concern is that if the concept shows significant viability/promise, they'll suddenly find themselves up against the Rolls Royce; GE; and Pratt & Whitney's of the world - companies with insanely deep pockets for R&D; companies that have the facilities, patents (eg. exotic alloys; additive manufacturing & processes), and run-history with already incredibly efficient jet turbine engines... at which point I'm not sure they'll be able to compete effectively, short of a buy-out/buy-in by person/s who also have very deep pockets.
It would awesome to combine the benefits of high voltage power from turbine generators with positively charged leading edges and negatively charged exhaust and negatively charged trailing edges. Super capacitors could also be utilized to dump massive amounts of pulsed electricity into either the turbines and or the respectively charged leading and trailing edges.
I'd test with a counter rotating stator both ways: a 2nd 3p AC induction motor and with 1 motor using 2 shafts connected by a planetary box. Tesla plaid motor should be able to drive both thus less parts
Looks promising. I'm not totally sure I understand how it is going to work. The concept plane has 6 engines. 4 of the supersonic and 2 for sub sonic I guess. Would love to see another video on how it going to work..
They are using an external turbojet engine to generate electricity right. And that electricity is then used to blows air. I don't see an advantage. Please clarify. 😊
The turbine section powers a generator and shoots a large amount of thrust out the back. The electricity from the generator runs the compressor section at the front of the engine. The compressor pressurizes the intake air for the turbine section so it can burn more air & fuel. This is the definition of a jet engine. Their principal modification is removing the traditional driveshaft between the turbine and compressor and replacing it with an electric generator & motor. This allows them to effectively change the gear ratios between the turbine and compressor. This is what the Pratt & Whitney PW1000 does but it does it with a transmission.
Something something energy losses from having to turn a big gear box… something something how expensive said gear box is… something something how said gearbox is very narrow in flight regimes
So is the turbine and generator getting it's energy from exhaust gasses being blow at high speed? more like a traditional jet engine but without a solid shaft going through the center of it. Or is the generator getting air from a separate duct and the engines are purely compressing and combusting gas and shooting it out the back? just curious because of the clip at 10:07.
First of all, if you're using LNG as the fuel, you can achieve the step-change in TSFC (for HSCT-like transpacific unrefueled range) by intercooling a turbojet or low-bypass turbofan, utilizing the cryogenic exergy of the fuel to greatly reduce the shaft power absorbed by the HPC (or increasing the OPR with no additional shaft power from the turbine) without running into issues with frosting in the troposphere (as in the SABRE precooler). Second of all, if you want to build a VCE with low TSFC throughout the entire mission, you can build a Turbine Bypass Engine, an engine with a Variable-Area Turbine Nozzle, a YF120-like engine with a Variable-Area Bypass Injector, or any number of other engines that don't use electric machines and power electronics to do a shaft's job. Electric transmission only makes sense for distributed propulsion applications where you're trying to increase propulsive efficiency by matching the distributions of thrust and drag (and thus overcome the system-level specific power/power density decrements inherent to these electrical systems). These people would be more useful doing VFX for Marvel movies than aeronautical engineering-unless they're money launderers, in which case they're actually doing a pretty good job of tech startup role play.
Seems like they're planning to do the whole portion (it briefly mentions vertical integration) from engine to jet to service. That's an interesting take as historically the engines are made by a subcontractor for the plane manufacturer who leases the planes to the airline who hires another subcontractor to maintain them. That's a lot of middlemen they'll be cutting out, so they maybe tackling the other issue of the Concorde, the expense of a ticket -- if the cost difference to get somewhere fast is signifcant, only the wealthy will be willing to pay it.
Interested to see if this will get adopted for commercial aircraft given supersonic flight has been possible for years but never made it past the Concorde. One of the concerns was the entry into supersonic speeds over residential areas due to the noise.
OK, just wanting to make sure I'm understanding the system correctly...you're using a gas turbine to spin a generator, the generated electricity is used to power two electric motors, one spinning the fan/compressor, the other spinning the turbine, and the purpose is to be able to spin the "cold" and "hot" sides independently to allow each "side" to run at whatever rpm is most effective at a given flight speed? I'm assuming a decent-sized battery is required, as well? I'm not going to poo-poo the concept, but I will say as someone who currently assembles jet engines for one of the world's major manufacturers, whatever you do keep things as simple as possible. The sheer number of components on a "traditional" jet engine is already staggering as is.
The variable operation speed is such a cool idea! Does the square nozzle not create heat concentration points along the corner lines? I know the raptor engine took longer to develop due (in part) to the exhaust nozzle giving them issues
have you considered patenting this engine to the military for future aircraft? this technology could legitimately improve the capabilities of current and future military aircraft by an exponential amount. this is the kind of engine my YF-42 Project needs.
this looks really interesting to me.. i really do not understand a tiny bit from this video and im not an engineer, but i wonder why big airplane companies didnt come up whith such an idea until now?.. i mean, big companies have the money and the people to reinvent things.. but a tiny start-up comes along with such an invention that big companies didnt come up with until now.. interesting
Because super sonic passenger airliners are just way too expensive and require massive investment that likely won't give returns. Manufacturers prefer to not go though the regulatory headaches and instead work on what they know works. For example even though the Concorde flew fantastic for years, it was not profitable at all and the airliners actually lost money
@@amazin7006 so do you mean that the next generations of passanger airlines like super sonic flight wont replace the passanger airplane industry that we know today in the future?
@@AlexFischer-b1e Certainly not in the near future. If it is ever adopted, then we will see it on military drones and experimental aircraft long before they are used on anything with passengers. Keep in mind there are a ton of other competing designs (from NASA, GE, and some Chinese company) as well as competing technologies like rotating detonation engines and different combined cycle engines, as well as even SpaceX getting into the hypersonic cargo delivery race.
Wonder if they could add a rankine cycle (or CLOSED Brayton cycle) after the gasturbine like in a combined cycle power station. However it might be much more compact as the bottoming cycle would have liquid methane moving through a heat exchanger in the condenser cooling the working fluid (water, glycerol, ...). The sink temperature would be far lower than the stp in a power station. The methane destined for the afterburner would be preheated as a bonus. Perhaps reusable drop tanks containing liquid nitrogen might provide open cycle cooling for the bottoming cycle whilst in non afterburning operation. The nitrogen could either be used directly as a thermal rocket engine or rooted into the unlit afterburner section to improve mass flow.
1. It's the fundamental limit of science ( there is no material other, than hydrocarbon that can output so much, energy ) economically. 2. The more steps you add, to a system, it will always give less, than it takes in. Good luck with your math.
using a High vibration and electric magnetic will push the boundaries of new invention and technology but the energy source must bind together as one I believe you can figure it out
So will your supersonic aircraft be based on the newer reduced sonic boom design so that hopefully it can be flown over land in the future when the new regulations are passed?
So since it's an apu powering an electric compressor there is no reason to keep the two in line. They can be completed separated to different parts of the aircraft resulting in new designs and placements in different shapes creating different airflow and compressibility areas

OK, just wanting to make sure I'm understanding the system correctly...you're using a gas turbine to spin a generator, the generated electricity is used to power two electric motors, one spinning the fan/compressor, the other spinning the turbine, and the purpose is to be able to spin the "cold" and "hot" sides independently to allow each "side" to run at whatever rpm is most effective at a given flight speed? I'm assuming a decent-sized battery is required, as well? I'm not going to poo-poo the concept, but I will say as someone who currently assembles jet engines for one of the world's major manufacturers, whatever you do keep things as simple as possible. The sheer number of components on a "traditional" jet engine is already staggering as is.
Amazing engine!
This engine should power a space plane (obviously first stage only). And it already uses LNG!
the first fire looks and sounds unreal. The camera shake and the slowdown make it feel like cgi footage.
The variable operation speed is such a cool idea!
Does the square nozzle not create heat concentration points along the corner lines?
I know the raptor engine took longer to develop due (in part) to the exhaust nozzle giving them issues
have you considered patenting this engine to the military for future aircraft? this technology could legitimately improve the capabilities of current and future military aircraft by an exponential amount. this is the kind of engine my YF-42 Project needs.
Impressive very nice.
this looks really interesting to me.. i really do not understand a tiny bit from this video and im not an engineer, but i wonder why big airplane companies didnt come up whith such an idea until now?.. i mean, big companies have the money and the people to reinvent things.. but a tiny start-up comes along with such an invention that big companies didnt come up with until now.. interesting
Because super sonic passenger airliners are just way too expensive and require massive investment that likely won't give returns. Manufacturers prefer to not go though the regulatory headaches and instead work on what they know works. For example even though the Concorde flew fantastic for years, it was not profitable at all and the airliners actually lost money
@@amazin7006 so do you mean that the next generations of passanger airlines like super sonic flight wont replace the passanger airplane industry that we know today in the future?
@@AlexFischer-b1e Certainly not in the near future. If it is ever adopted, then we will see it on military drones and experimental aircraft long before they are used on anything with passengers. Keep in mind there are a ton of other competing designs (from NASA, GE, and some Chinese company) as well as competing technologies like rotating detonation engines and different combined cycle engines, as well as even SpaceX getting into the hypersonic cargo delivery race.
Wonder if they could add a rankine cycle (or CLOSED Brayton cycle) after the gasturbine like in a combined cycle power station. However it might be much more compact as the bottoming cycle would have liquid methane moving through a heat exchanger in the condenser cooling the working fluid (water, glycerol, ...). The sink temperature would be far lower than the stp in a power station. The methane destined for the afterburner would be preheated as a bonus. Perhaps reusable drop tanks containing liquid nitrogen might provide open cycle cooling for the bottoming cycle whilst in non afterburning operation. The nitrogen could either be used directly as a thermal rocket engine or rooted into the unlit afterburner section to improve mass flow.
Super-Heating the bottoming cycle in the combustion chamber is also a thought as it might allow a higher fuel air ratio in the combustion chamber.
It sounded like a big pulsejet.
Are you sure he did that partially?
Kind regards,

I'd think the losses would be too high to see a 60% range increase
Amazing! Super cool
1. It's the fundamental limit of science ( there is no material other, than hydrocarbon that can output so much, energy ) economically.
2. The more steps you add, to a system, it will always give less, than it takes in. Good luck with your math.
Not a single comma in your comment is correct
Superawesomeness, and congrats to the Team on this successful benchmark!
So Boom Supersonic weren’t kidding with the efficiency 😂
looking forward to using this in an engine swap in my Miata
Super smart Idea
using a High vibration and electric magnetic will push the boundaries of new invention and technology but the energy source must bind together as one I believe you can figure it out
Nice I'm still doing it in the garage. Still at RC scales.
So will your supersonic aircraft be based on the newer reduced sonic boom design so that hopefully it can be flown over land in the future when the new regulations are passed?
I think they're targeting trans-Atlantic flights
I think the point of the engine being efficient at more speeds signals they are going for the more traditional route.
So since it's an apu powering an electric compressor there is no reason to keep the two in line.
They can be completed separated to different parts of the aircraft resulting in new designs and placements in different shapes creating different airflow and compressibility areas
Underrated
Calculate air density moving through the engine and you could then calculate a better fueling table.

Ultra controllable hybrid jet engine running on LNG. WHOOAAH
The only problem is scaling. The size of wire you will need to do what even the smallest jet engines do is going to be very hard.
